To @ZZ whom z' may concern:

Be it known that l, WILLIAM A.. Kinney., a' citizen of the UnitedStates, residing et Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented new and useful improvements inBurners, of which the ollovfinggl is e speeil'ioationn lEhe inventionrelates to a burner., und more particularly to the class of oil orhydrocarbon burners.

The primary object of the invention is the provision of a burner of thischaracter wherein the construction thereof siphons the oil from areservoir or tank Without the presence oit. pressure Within the latter,the intensity of the flame of the lburner being governed 'by valvesarranged therein.

Another object of the invention is the nro vision of u hunner of thisCharacter wherein the oil ejected vtherefrom is broken up into a finespray and is forced into the furnace with great velocity.,

A still further object of the invention is the provision of a burner o'.this character which is extremely simple in construction, thoroughlyreliable and eiicient in its opera.v tion, strong, durahle andinexpensive in manufacture.

@ther objects will he in part obvious and in part hereinafter set forth.

The invention accordingly consists in the `features of construction,combination of elements and arrangement of parts which will heexemplified in the construction hereinafter described, und the scope ofthe application of which Will be indicated in the nu pended claim.

ln the accompanying drawings:

Figure l is a side elevation oi a burner constructed in accordance withthe invention, showing the oil lead and the air lead with a heating coiltherein;

Fig. 2 is a vertical longitudinal sectional View through the burner;

Fig. 3 is a vertical longitudinal sectional View showing the burnernozzle and the valve in their relative positions.

Similar reference characters indicate correspondingr parts throughoutthe several views of the drawinvf.

Referring! tothe drawing in detail, the burner comprises u body A whichis preierably in the form of n fil-shaped union provided with anexten-nelly threeded end 5 on which is detachehly mounted e nap semebeing formed with e reducedinnerenelly threaded portion 'l in which 1eengaged or tapped the air supply lead 8 provide-xl With a heating);member 9 adapted heet the air supplied prior to its entrance into thehurneiyj this inenting member 9, Vfor the pun pose oi illustration'lo-eine; shown as, in coil forni, and Il to have it understood thetdonot limit myself te this particular coil construction as itl isnecessary in some streight section or heating enses to use a member.

The body A. at the end w opposite the end 5 is formed with internalthreads. ll for the adjustable 'and detachable engagement of anoutwardly tapered nozzle l2 with seid hotly., the inner end portion ofthe nozzie 12 lheling/j formed with e nipple i3 which has formedinteriorly thereof a tapered valve seat 14E,

while located. within the hodylis a. remo'ifahle' nozzle 14', the sameming held in suoli body/2 by `the cop tf, and this nozzle directs theair to the nozzle l2 which forms the tip of the burner, the nozzle 141-heine' provided with e tapering valve end 155 wliieli engages in thevalve sent ifi in the yinigopie end. 13 et said.

vnozzle 12, the latter being edjusteble in the body to regulate the feedof oil 4from the burner, which oil is admitted to the body A through alead 16 which is' tapped into the internally threaded end 17 of seidbody il of the burner.

in the operation of the burner., eir is 'admitted thereto from the lead8`v Whioh air is preheated in the member 9 and is delivered from anysuitable source. The entre-nce oi air into the body A of the burnere'eects a yae'uuni therein sothat the oil is lifted from the lead L6into. the body A and is mixed with the air, which forces the sameoutwardly through the nozzle 12 with great velocity and et this nozzlelll the oil is ignited1 The density of the oil is governed ley theadjustment of the nozzle i2,whioh reef lates the relation of the nipplei3 withthe valve end 15 of the inner nozzle l?? as will 'be clearlyapparent,

From' the foregoing description, taken in connection with theaccompanying drawing? the construction and operation of the hereindeem-lod lun-ner Will he readily annuiL ont und, therefore, a moreextended cui/)lanaion hns heen omitted.

Having thus described my invention, i Claim:

T he con'ibination otl a body having an interiorly locatedc},\'lindri::al elianiloor7 there 'being4 an oilvport leading' into thechainher at the Side tliereoil and at apoint between the ends thereof, aforward nozzle attaeheol to one end ot' 'the body and having; an annularflange extending' into the chamber, the exterior enraee of the flangebeing;r cylindrical and spaced throughout its length from and parallelwith the eide wall ot' the chainher, said flange extending complete-lyacross the oil port andepaced therefrom, the in-l terior Surface' of thefiange heine; conical, said nozzle having' at its outer portion a llorelthe inner end of which merges into the inner Wall surface of theliange, a Seeoiul nozzle attached to the opposite end oi' the body andprovided at its inner end with a nipple which extends into the ehani'herand enters within and extends rearwardly ot' the Hanne otl'tvleyiistmentioned nozzle to reet in lapped relation to said nozzle opposite thetull diameter et' the oil port, said nipple having: an exterior fonieal.eurfaee which is l parallel with and spaced from the interiorconical surface of the flange, the exterior Surface of tlie'ninnlebeine; eonieal throinqgli-v ont the length oi the nipple, there beingprovided in the second mentioned nozzle a longitudinally disposedA borewhich is in alinenient 'with the een-ter of the loore in the iirstmentioned nozzle, the diameter of the bore in the first mentioned nozzlebeing greater-than that of the here in the second mentioned nozzle,whereby a stream ot air passingl from one nozzle to the other at greatvelocity will draw a *volume of oil into the chamber of the body againstthe force of If lravity and elleet a mixture of the air and oil wit-hinthe forward nozzle whereby the mixture when ignited at the end of theforward nozzle will produce a :solid pencil. of flame.
